3D-Tool
With 3D-Tool you can check 3D models without an expensive CAD system. The intuitive operation and user-friendly program interface do not require any special CAD knowledge. Simple mouse actions allow you to zoom and rotate models, show and hide parts and assemblies, and create cross-sections and exploded views. With 3D-Tool you print drawings true to scale, edit or delete drawing elements and add dimensions and markups. 3D-Tool supports 2D drawings in the formats DXF, DWG, HPGL and, in the Premium version, also drawings from CATIA and SolidWorks. Use 3D-Tool to coordinate constructions in the company as well as with customers and suppliers. 3D-Tool publishes models as directly executable EXE files or as DDD files for the 3D-Tool Free Viewer. Both EXE files and the free Viewer have the 3D-Tool tool palette. 3D-Tool also creates 3D PDF files for the widely used Adobe Acrobat Reader. In this way, 3D models also reach users who do not want or are not allowed to install special software.

CityCAD Viewer
CityCAD Viewer is a free tool for opening and exploring URB-format models created with CityCAD. It is completely free of charge and does not require any user registration or product activation. You cannot draw or modify elements such as streets or buildings, but you can use CityCAD Viewer to change assumptions on costs, values, sustainability information and other settings for each land use. We created CityCAD Viewer to help CityCAD users share their city models with colleagues, clients and other stakeholders. It is intended to enable easier collaboration on masterplanning projects. Open, explore and save CityCAD models. Select elements in a CityCAD model and view information about them. Change the group or phase of elements in a city model. View all city analysis panels (except the ‘advisor’ tab and advanced appraisal features). Add and edit simple costs and values to elements. Export images, reports, data and KML files.
